Taiwan-Japan Connection
To launch the International IOWN APN, Chunghwa Telecom connected its headquarters to a landing station in Taiwan, which in turn was linked to a landing station in Japan. NTT connected its Musashino R&D Center to a landing station in Japan. Both CHT and NTT then established a connection between each other and confirmed its completion with stable communication.
Technical Specifications
The IOWN APN, utilising All-Photonics Network technology, delivers a 100 Gbps optical path with a round-trip time (RTT) of 33.84 milliseconds. It adheres to the Open All-Photonic Network Functional Architecture (OAA) defined by the IOWN Global Forum, enabling advanced device interconnectivity.
Network Architecture
The network architecture and equipment of the International IOWN APN supports for OAA, Open All-Photonic Network Functional Architecture, which is published by IOWN Global Forum, and the various devices are interconnected, the companies said in a joint statement.
Demonstrations and Disaster Countermeasures
Under this cooperation, Chunghwa Telecom will use the international APN to demonstrate low-latency interactive immersive entertainment at the NTT R&D Forum 2024. NTT will provide data backup and replication services for disaster countermeasures to support Smart Factory and other initiatives, primarily targeting semiconductor and manufacturing industries in Taiwan and Japan, the companies explained.
